[英]Same repository method with different signature in spring-data-rest
我有一個場景，我有一個看起來像這樣的抽象存儲庫。
@NoRepositoryBean
public interface AbstractObservationRepository<T extends AbstractObservation, E extends Serializable> extends JpaRepository<T, E> {
Set<T> findByOwnerId(String id);
Page<T> findByOwnerId(String id, Pageable pageable);
}
現在，這個抽象存儲庫已被另一個存儲庫擴展，如下所示（此處Fall實體類擴展了AbstractObservation ）。
public interface FallRepository extends AbstractObservationRepository<Fall, String> {
}
我正在使用 spring-data-rest 來訪問這些存儲庫，而無需編寫控制器和服務。 但是，當我嘗試訪問Fall rest 存儲庫端點http://localhost:8080/falls時，出現以下錯誤。
java.lang.IllegalStateException: Ambiguous search mapping detected. Both public abstract java.util.Set com.intelliaide.mycaren.repository.observation.AbstractObservationRepository.findByOwnerId(java.lang.String) and public abstract org.springframework.data.domain.Page com.intelliaide.mycaren.repository.observation.AbstractObservationRepository.findByOwnerId(java.lang.String,org.springframework.data.domain.Pageable) are mapped to /findByOwnerId! Tweak configuration to get to unambiguous paths!

我怎樣才能解決這個問題？
你可能不想要這個方法： Set<T> findByOwnerId(String id); . 我認為您不能將存儲庫中的兩種不同方法映射到相同的底層findBy{something} 。
如果你真的想要返回整個集合，創建一個非常大的頁面請求： new PageRequest(0, Integer.MAX_VALUE); ，然后轉換為 Set new HashSet<ScanEntity>(page.getContent()) 。
值得一提的是，檢索所有結果可以被認為是不好的做法。 通常，您想編寫一個數據庫查詢或使用另一個存儲庫/實體管理器函數，以便數據庫可以處理工作並且您不會將一堆東西加載到內存中。 即使你的收藏中沒有很多元素，我目前正在進行一個項目，有人這樣做了，一開始還不錯。 但是后來我們需要填充列表的列表，突然我們的頁面需要幾秒鍾才能加載，因為我們正在執行 100 次查詢而不是 1 次。我們現在必須修復。
有沒有辦法在spring-data-rest存儲庫方法上驗證方法參數？
